ATTACHMENT FOR BALING -PRESSES.

SPECIFICATION forming part of Letters Patent No. 522,208, dated July 3,1894.

Application filedMarcli 9,1893. Serial N0.465,334- (No model.) 7

To aZZ whom it may cancer-m Be itknown that I, JOHN J. HISER, a citizenof the United States, residing at Arcadia, in the parish of Bienvilleand State of Louisiana, have invented a new and useful'Attachmeut forBaling-Presses, of which the following is a specification.

My attachment relates to improvements in baling-presses, and moreespecially to that class thereof which employs a tramping-attachment asillustrated in United States Patent No. 443,995, granted me January 6,1891.

The objects of my present improvements are to provide a mechanism foroperating the tramping-attachment, which mechanism'is so constructed astobe adapted to be operated by a mechanical -power'; to construct themechanism in such manner as to raise and lower the tramping-plunger, andto accomplish this reversal of movement under the guidance of theoperator and in a convenient manner; and furthermore to provide for aretention or locking of the plunger in a depressed position without astoppage of the motive-power or mechanism for operating said plunger.

With these and other though minor objects in view the invention consistsin certain features of construction hereinafter specified andparticularly pointed out in the claims.

Referring to the drawingsz-Figure 1 is a perspective view of a pressprovided with my improvements. Fig. 2 is a Vertical transverse sectionalview ofthe same looking toward the gearing. Fig. 3 is a top plan view.Fig. 4 is a side elevation.

Like numerals of reference indicate like parts in all the figures of thedrawings.

Upon a pair of transverse base-sills l, or it may be any other suitablesupport, there is located a pair of parallel longitudinal sills 2, whichare bolted to the base-sills and serve to connect the same. Inthepresentinstance there arises from the'sills 2 and is-bolted near theends thereof a pair of vertical uprights or posts 3, which uprights areconnected near their middles by a cross-beam 4. Supported upon thelongitudinal sills 2 and the crosspiece 4 is the baling-chamber 5, thesame, as usual, being provided with the opposite removable sides andends 6 and 7 respectively.

the tram ping-plunger. I would here state that their centers, in thisinstance, with single re.-

Located in the chamber 5 isthe follower 8, which is operated through themedium of a threaded feed-shaft 9 designed to be rotated through anysuitable power, as will be ob- Vi0l1S.'

Loosely hinged-between the longitudinal sills 2 and between the ends ofthe balingchamber anduprights 3 is a pairof vertical standards 11, whichare connected and embraced at their upper ends by the cross-pieces 12,whose under sides are connected by slats,

whereby the whole forms a swinging platen against which the follower inthe act of pressing the bale operates and which is capable of beingswung to the front of the press out of line with the baling-chamber soas not to interfere with the tramping-plunger 13 that is located abovethe platen.

Thus far I have described the ordinary construction of this class ofpresses, and I. will now proceed to describe my improvements,which,'asbefore stated, are directed only to a suitable mechanism for operatingif desired this mechanism may be supported independent of the press,that is by the woodwork above the same, instead of, as in the presentinstance, by means of the uprights 3. In the former case of course itwill be understood that the uprights 3 would be dispensed with as theywould serve no useful function in connection with my mechanism, butperhaps might be employed inconnection with the baling-chamberitself,that is merely acting as a support therefor. However, it would be safeto say that the uprights would be dispensed with entirely in that othermeans could be better devised for such purpose.

The uprights 3 are connectedby apair of parallel transverse cap-beams14, and between the ends of these beams are interposed and boltedhorizontal cross-arms 15. The rear edges of the cap-beams 14 areprovided at cesses 16 which are vertically opposite each other. In theserecesses there is seated a metal wear-plate 17, the upper and lower endsof said plate overlapping the upper and under sides of the upper andlower cap-beams, 100

respectively. Set bolts 18 are threaded in countersunken plates 19located in the front edges of the cap-beams, and at their rear ends bearupon said wear-plate and serve to adjust the same in a manner obvious.Intermediate cross-beams 20 pass between the cap-beams at opposite sidesof the wear-plate, and said intermediate cross'beams are provided attheir rear ends with transversely-disposed bearings 21, which bearingsare also produced and indicated at 21 in the rear ends of the horizontalcross-arms 15. In these bearings 21 there is journaled for looserotation a horizontal shaft 22, one of whose ends projects beyond theend cross-arm through which it passes. Mounted upon the shaft 22 betweenthe intermediate cross-arms is a spur-gear or pinion 23, and engagingwith the same is the series of teeth 24 formed on the rear face of thestem 25 of the tramping-plunger, so that, as will be obvious, as theshaft 22 and its pinion 23 are revolved the movement is imparted to thetramping plunger-stem, and hence the tramping-plunger raised or loweredin accordance with the direction of rotation of the shaft. A small drum26 is located upon the shaft 22 at one side of the pinion, and securedto the drum is one end of a rope 27, the remaining end passing over aloose pulley 28, which is journaled in a horizontally-disposed arm 29that projects from the upper cap-beam 14 in rear of the press. To thelower end of this rope a counterbalancing weight 30 is se cured, thesame being designed to counterbalance the weight of the plunger and itsstem. The extended end of the shaft 22 has mounted thereon a'spur-gearwheel 31 and outside of or beyond the same a belt-pulley 32, the pulleyand gear both being fast upon the shaft. A hand-lever 33 is pivoted orfulcrumed as at 34 below the spur-gear 31 and upon the upright adjacentthereto, and at its rear end is provided with a transverse tooth 35,which when the front end of said lever is depressed is consequentlyelevated into engagement with an adjacent tooth of the spurgear 31 andhence locks the spur-gear, the shaft 22, and the plunger and its stemrigid against movement in either direction.

To the upper and lower edges of that crossarm 14 upon which the gearingdescribed is located and at the front end thereof there is located apair of parallel horizontal ways 36 in which there is mounted forreciprocation a sliding-bar 37. A hand-lever 38 is pivoted at its upperend, as at 39, to one of thestationary ways, and below said point ofpivot is, by means of a link 40, loosely connected with saidsliding-bar, the ends of the link being pivoted respectively to thelever and to the bar. A locking-bar 40 is arranged below the gearing andat one side of the hand-lever, and said locking-bar has its inner faceprovided with a series of three notches 42, 43, and 44.

A metal-bushing is located in the slidingbar 37 near the inner or rearend thereof, and said bushing aligns with bearing-openings 38 formed inthe front ends of the intermediate cross-arms 20, the bearing-opening inthat cross-arm most adjacent to the slidingbar being elongated so thatthe short shaft 46 which is mounted in the bushing and saidbearing-openings and passes through and beyond the former is free tomove laterally at its outer end. The shaft 46 is provided with a smallpinion 47 at one side of the same and with a small pulley 48 which isconnected to the pulley 32 by a belt 49, and is further provided with adrive-pulley 50 over which passes a belt 51 leading from any suitablemotor and serving to drive said pulley continually, when the press is inoperation, in the direction indicated by the arrow.

This completes the construction of the attachment, and its operation isas follows: The swinging platen is thrown to the front so as to be outofthe way of the tramping-plunger, and as the cotton is deposited in thebaling-chamher the plunger reciprocates, packingeach portion preparatoryto the final compression. The manner of securing a reversal of themovable plunger by a continuous rotary motion of the drive-pulley 50 isas follows: By throwing the hand-lever 38 to the rear and intoengagement with the notch 44 of the locking-bar it will be seen that thespur-gears of the two shafts will intermesh so that the motion from thesmaller gear or that upon the drive-shaft will cause an opposite motionof the plungeroperating shaft and hence said plunger will be loweredinto the baling chamber. It will be further seen that this rearwardmovement of the drive-shaft so as to intermesh the two gears will causethe belt 49 to become slack and hence inoperative. When the plunger hasdescended and a suflicient pressure been brought to bear and it isdesired to elevate the plunger the hand-lever is again grasped by theoperator, swung to the front and engaged with the outer notch 44. Itwill be seen that such movement upon the part of the lever will causethe power-shaft to be swung to the front and hence a disengagement ofthe gears takes place. The disengagement of the gears of course preventsmotion being imparted from the power-shaft to the driveshaft through thegears, but at the same time it will be noticed that the belt connectingthe two pulleys of the shafts will become tightened and operative, and,as is Well known, a similar movement will be communicated from thepulley of the power-shaft to that of the drive shaft incontradistinction to the reversal movement caused by the engaging andrevolving gears. In this manner the plunger is elevated ready fortramping a subsequent deposit of material in the press. It at any timeit is desired to retain the plunger either raised or lowered it issimply necessary to swing the hand-lever to the central notch 43 whichwill sufficiently slacken the belt to prevent communicating motion andyet will not engage or intermesh the teeth of the gears so that nomotion whatever will be imparted, but the power-shaft will run idle.When the plunger is depressed and it is desired to hold or look the samein such position for any purpose this operation is followed, that is thelever is brought to the central notch and im'- mediately thereafter thelocking-lever is depressed at its front; end and consequently its rearend elevated into engagement with the teeth of the gear upon thedrive-shaft,

From the foregoing description in connection with the accompanyingdrawings it will be seen that I have provided a trampingplungeroperating mechanism of cheap and simple construction that may be locatedupon or supported above the press and independent thereof if so desired,which mechanism is adapted to be mechanically operated for the purposeof raising and lowering the trampingplunger and is capable of beingreversed or its movement arrested for a change of direction of the powergear or motor, and is capable of being locked against movement while atthe same time said motor is operated.

I do not limit my invention to the details of construction herein shownand described, but hold that I may vary the same to any degree or extentwithin the scope of persons conversant with this class of machinery orthe skilled mechanic.
